  "summary": "Reviewed the x86-64 assembly implementation of `curve25519_x25519base_alt` / `curve25519_x25519base_byte_alt`, including its scalar mangling, constant-time table lookup, field arithmetic, and inline modular inversion path. I found no concrete malicious or supply-chain indicators in this target file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, or hidden subprocess execution.",
